Summary
Protein Function
Legumain is a cysteine protease from the C13 family of the CD clan of proteases (MEROPS). It uses a catalytic triad of Cysteine-Histidine-Asparagine in its active site to perform covalent proteolysis of its substrate.
It catalyses the following chemical reaction: Hydrolysis of proteins and small molecule substrates at -Asn-Xaa- bonds. Both plant and animal legumains are most active in acidic environments. (From Wikipedia)
